Convert it to Bitcoin, the last thing you want is to be exposed to a ton of shitcoins and Bitcoin forks (such as BCH, or BTG) where you have no clue the fate of the coin. It's not like we can really say much about Bitcoin, but at least we know that it is the REAL bitcoin.

Take your free Bitcoin and run, do as you please with that though. I sold off all of my BCH and plan on selling off any other fork to just convert to BTC and then to USD-- I'd advise doing the same if I were you.
